Abstract

The storage box (10) is formed by bending a sheet-like body of a predetermined shape into a rectangular parallelepiped shape composed of a front surface section (12), a back surface section (13), a flat surface section (14), a bottom surface section (15), a right side surface section (16), and a left side surface section (17). In assembly, a removal part (27) which is a part of the lower side of the front lower folded piece (28) and is cut by the needle hole (41) in unsealing is fixed to the lower part of the front piece (22) covering the front part (12). In addition, the left edge of the removed portion (27) overlaps the left edge of the front sheet (22). A specific front edge (58) is formed by cutting a semi-oval notch in the front edge of a bent piece (35) that covers the upper part of the left side surface section (17). Therefore, the specific front edge (58) is separated from the position of the left side edge of the front sheet (22) to the rear. Thus, since a space is secured between the left edge of the removal portion (27) and the specific front edge (58), the left edge of the removal portion (27) can be easily grasped when unsealing the same.

Detailed Description

Fig. 1 is a schematic perspective view showing an external appearance of a storage box according to embodiment 1 of the present invention, and fig. 2 is an expanded view of the storage box shown in fig. 1 as viewed from a front surface thereof.

Referring to these drawings, the storage box 10 is formed by folding a sheet-like body 11 made of a paper blank or the like that is spread out in a predetermined shape into a rectangular parallelepiped shape having a front surface as viewed from the direction of the arrow in fig. 1 and a front surface portion 12, a back surface portion 13, a flat surface portion 14, a bottom surface portion 15, a right side surface portion 16, and a left side surface portion 17.

Since the specific configuration is reversed right and left except for the portion relating to the eyelet 41 and the removal portion 27, which will be described later, only the left side of the storage case 10 will be described.

First, the sheet-like body 11 includes a front sheet 22 covering the front portion 12 of the housing box 10. The sheet-like body 11 further includes a left side rear bent piece 32 which is connected to the left edge 42 of the front sheet 22 so as to be bendable when unfolded and is bent rearward with respect to the front sheet 22 so as to cover approximately one-third of the left and right sides from the front of the left side surface portion 17 when assembled.

The sheet-like body 11 further includes a bottom surface piece 25 that is connected to the lower edge 52 of the front surface piece 22 so as to be bendable when unfolded and is bent so as to cover the bottom surface portion 15 when assembled. The sheet-like body 11 includes a left side upper bent piece 35 which is bent upward with respect to the bottom sheet 25 so as to be connected to the left side edge 45 of the bottom sheet 25 so as to be bendable when unfolded and to cover substantially the entire surface of the left side surface portion 17 when assembled, and is fixed to the outer surface of the left side rear bent piece 32 by an adhesive or the like. The left side upper folded piece 35 is different from the side panel 115 of the conventional package box 90 in that a semi-oval notch 38 is formed along the front edge 48 of the left side upper folded piece 35. The effect of providing the notch 38 will be described later.

The sheet-like body 11 is provided with a back surface sheet 23 which is connected to the rear edge 55 of the bottom surface sheet 25 so as to be bendable when unfolded and is bent so as to cover the back surface portion 13 when assembled. The rear surface sheet 23 is provided with a left side front bent piece 33 which is connected to the left side edge 43 of the rear surface sheet 23 so as to be bendable when unfolded, is bent forward relative to the rear surface sheet 23 so as to cover substantially the entire surface from the rear of the left side surface portion 17 when assembled, and is fixed to the inner surface of the left side upper bent piece 35 by an adhesive or the like.

The sheet-like body 11 includes a flat sheet 24 that is connected to an upper edge 53 of the back sheet 23 so as to be bendable when unfolded and is bent so as to cover the flat surface portion 14 when assembled. The lower front-surface folding piece 28 is connected to the front edge 54 of the flat sheet 24 so as to be foldable when unfolded, and is folded downward so as to cover the entire surface of the front surface sheet 22 when assembled. The lower left-side bent piece 34 is connected to the left edge 44 of the flat piece 24 so as to be bendable when unfolded, and is bent downward so as to cover the upper half of the outer surface of the upper left-side bent piece 35 when assembled.

Here, the front lower folded piece 28 is divided into a remaining portion 26 occupying approximately two fifths of the upper side and a removed portion 27 occupying approximately three fifths of the lower side, with the cuttable needle hole 41 formed parallel to the front edge 54 of the flat piece 24 as a boundary. In order to prevent the storage box 10 from being opened unintentionally during transportation or the like at the time of assembly, a part of the removal portion 27 is fixed to a part of the lower portion of the top sheet 22 with an adhesive. The adhesion strength is such that the removed portion 27 is separated by hand. In the present embodiment, the front lower bent piece 28 is configured such that the removed portion 27 is cut off from the left to the right, and therefore, although not shown, the needle hole 41 is shaped so as to be easily cut off in the right direction of the removed portion 27.

The remaining portion 26 includes a 2 nd left side surface rear bent piece 36 that is connected to the left side edge 46 of the remaining portion 26 so as to be bendable at the time of expansion and is bent rearward with respect to the remaining portion 26 so as to cover substantially the entire surface of the left side surface lower bent piece 34 at the time of assembly. The 2 nd left side rear bent piece 36 is fixed to the inside of the left side lower bent piece 34 by an adhesive or the like. Further, a cutting blade 40 made of metal, paper, or the like and extending in the longitudinal direction is attached to the inside of the residual part 26 so that the tip of the cutting blade 40 protrudes from the tip of the residual part 26. The front end of the cutting blade 40 attached inside the remaining portion 26 is covered with the removed portion 27 in an unopened state.

Fig. 3 is an enlarged perspective view of a left side portion of the housing box shown in fig. 1, and fig. 4 is an enlarged sectional view taken along line IV-IV shown in fig. 3.

Referring to fig. 3, as can be seen from the developed view of fig. 2, the left side edge 47 of the removed portion 27 is arranged to overlap the left side edge 42 of the front sheet 22. Further, the front edge 48 of the left side upper folded piece 35 is aligned with the left side edge 42 of the front surface piece 22 at a connecting portion 56 with the bottom surface piece 25, and a semi-oval notch 38 is formed above the connecting portion 56 to constitute a specific front edge 58. Therefore, the specific front edge 58 is spaced rearward from the position of the left side edge 42 of the front panel 22.

At least a part of the specific leading edge 58 is exposed from the left side lower bent piece 34 and is disposed at least a part of a position corresponding to a part of the left side edge 47 of the removed portion 27.

Next, referring to fig. 4 as well, when opening the container box 10, the left edge 47 of the removed portion 27 is pinched, and the removed portion 27 is separated along the needle hole 41 against the adhesive fixation, as in the case of the conventional packaging box 90. At this time, since the specific front edge 58 is spaced rearward from the position of the left side edge 42 of the front sheet 22, a space 59 is secured between a part of the left side edge 47 of the removed portion 27 and the specific front edge 58. Therefore, by abutting a finger against the space 59, it becomes easy to press the finger against the left edge 47 of the removal portion 27, and it becomes easy to pinch the removal portion 27.

Further, by forming the specific front edge 58 as the semi-oval notch 38, the distance from the position of the left side edge 42 of the front sheet 22 to the rear is substantially constant. Therefore, the distance of the left side edge 47 of the removal portion 27 from the specific leading edge 58 is stabilized, and thus the grasping ease of the removal portion 27 is stabilized.

Further, since the front edge 48 of the left side upper bending piece 35 positioned below the specific front edge 58 is configured to be aligned with the left edge 42 of the front surface piece 22 at the connection portion 56 with the bottom surface piece 25, the connection strength of the left side upper bending piece 35 of the connection portion 56 can be secured, and therefore, the assembly strength of the storage box 10 is improved.

In the storage box 10 configured as described above, a wound material formed by winding a sheet made of aluminum foil or the like, not shown, can be stored.

In use, similarly to the conventional package case 90, the left edge 47 of the removed portion 27 of the storage case 10, which is easily grasped, is grasped, and the removed portion 27 is separated along the needle hole 41 against the adhesion and fixation. Then, the storage case 10 is opened, and the distal end of the cutting blade 40 is exposed. Next, the flat sheet 24 is rotated in a direction toward the rear surface portion 13 with the upper edge 53 of the rear sheet 23 as the axis, and the storage case 10 is opened. Then, the curl stored inside the storage box 10 is exposed, and therefore the sheet is pulled out from the curl by a desired length. Then, by pressing the flat sheet 24 after returning to the original position of the flat portion 14, the remaining portion 26 is lowered, and the tip of the cutting blade 40 is brought into contact with the sheet pulled out to a desired length, whereby cutting can be performed.

By providing the removed portion 27 in this way, it is possible to provide the cutting blade 40 without exposing it until the package box 90 is opened, and to easily open the package box 10 by cutting the removed portion 27.

Fig. 5 is an enlarged perspective view of a left side portion of the storage box according to embodiment 2 of the present invention, and corresponds to fig. 3.

In embodiment 2, the configuration is basically the same as that of embodiment 1 except for the specific front edge 68 of the storage box 10, and therefore, the description thereof will not be repeated, and the description will be centered on the difference therebetween.

Referring to the drawings, the front edge 48 of the left side upper folded piece 35 of the storage box 10 is substantially adjacent to the lower end of the left edge 42 of the front piece 22 and the lower end of the left end 47 of the removed part 27 at the connecting portion 66 with the bottom piece 25. The specific front edge 68, which is at least a part of the front edge 48 of the left upper bending piece 35 exposed from the left lower bending piece 34, is formed by cutting off a straight line extending obliquely rearward and upward from the connecting portion 66 with the bottom surface piece 25 as a base point. Thus, the specific front edge 68 is spaced rearward from the position of the left side edge 42 of the front sheet 22 as it faces upward. At least a part of the specific leading edge 68 is exposed from the left lower bent piece 34.

Next, when the container box 10 is opened, the left edge 47 of the removed portion 27 is pinched to separate the removed portion 27 along the needle hole 41 against the adhesive fixation, as in embodiment 1. At this time, since the specific front edge 68 is spaced rearward from the position of the left side edge 42 of the front sheet 22, a space 69 is secured between a part of the left side edge 47 of the removed portion 27 and the specific front edge 68. Therefore, by abutting a finger against the space 69, it becomes easy to press the finger against the left side edge 47 of the removal portion 27, and it becomes easy to pinch the removal portion 27.

The subsequent use is similar to embodiment 1 in the step of cutting the sheet such as aluminum foil stored in the storage box 10.

Fig. 6 is a schematic perspective view showing an external shape of a storage box according to embodiment 3 of the present invention, and corresponds to fig. 1.

In embodiment 3, the configuration is basically the same as that of embodiment 1 except for the configuration relating to the removed portion 27 and the specific leading edge 78, and therefore, the description thereof will not be repeated, and the description will be centered on the difference therebetween.

Referring to the drawing, the 2 nd eye 71 is provided in the removed portion 27 of the bent piece 28 below the front surface of the storage box 10 so as to be parallel to the eye 41. Taking this 2 nd eye 71 as a boundary, the removed part 27 is divided into a removed piece 76 occupying about the upper half and a residual piece 77 occupying about the lower half.

In addition, in order to prevent the storage case 10 from being opened unintentionally during conveyance or the like during assembly, the residue sheet 77 is fixed to a part of the lower portion of the top sheet 22 by an adhesive or the like. Thereby, the removal sheet 76 is sandwiched between the residual part 26 and the residual sheet 77, and has a belt-like structure that is not fixed to the front sheet 22.

In this embodiment, the front lower bent piece 28 is configured such that the removed piece 76 is cut off from the left to the right, and therefore, the shape of the 2 nd eyelet 71 is a shape that is easily cut off in the right direction, as in the eyelet 41, although not shown.

Further, the front edge 48 of the left side upper bending piece 35 is aligned with the left side edge 42 of the front panel 22 at the connecting portion 56 with the bottom panel 25. Further, a specific front edge 78, which is a cut out semi-oval shaped cutout, is disposed at a position corresponding to the left edge 73 of the removal piece 76 on the front edge 48 of the left side upper folded piece 35.

At least a part of the specific leading edge 78 is exposed from the left lower bent piece 34.

Next, when opening the container box 10, the left edge 73 of the removed piece 76 is pinched and the removed piece 76 is cut along the needle eye 41 and the 2 nd needle eye 71, as in embodiment 1. At this time, since the specific front edge 78 is spaced rearward from the position of the left side edge 42 of the front sheet 22, a space 79 is secured between the left side edge 73 of the removal sheet 76 and the specific front edge 78. Therefore, by placing a finger against the space 79, the finger is easily pressed against the left edge 73 of the removal piece 76, and it becomes easy to grasp the removal piece 76.

Further, as described above, the removal sheet 76 is sandwiched between the residual part 26 and the residual sheet 77, and the residual sheet 77 is bonded and fixed to a part below the front sheet 22 at the time of assembly, so that the removal sheet 76 does not need to be bonded and fixed. Therefore, when the storage case 10 is opened, the removal piece 76 can be cut without overcoming the adhesion fixation, and the removal piece 76 can be easily separated.

Further, by forming the specific front edge 78 as a semi-oval notch, the distance to the rear from the position of the left side edge 42 of the front sheet 22 is substantially constant. Therefore, the distance of the left side edge 73 of the removal sheet 76 from the specific leading edge 78 is stabilized, and thus the grasping ease of the removal sheet 76 is stabilized.

Further, since the front edge 48 of the left side upper bending piece 35 positioned below the specific front edge 78 is configured to be aligned with the left edge 42 of the front piece 22 at the connection portion 56 with the bottom piece 25, the connection strength of the left side upper bending piece 35 of the connection portion 56 can be secured, and therefore, the assembly strength of the storage box 10 is improved.

The subsequent use is similar to embodiment 1 in the step of cutting the sheet such as aluminum foil stored in the storage box 10.

In the above embodiments, the specific front edge is provided on the left side of the storage box, but the entire storage box may be inverted left and right to provide the specific front edge on the right side. In this case, the removed portion or the removed portion may be configured to be cut from right to left.

In the above embodiments, the front edge, the removed portion, or the removed piece is specified, and the entire storage box has a left-right asymmetrical structure. In this case, the specific front edge may be disposed on both the left and right sides, and the removed portion or the removed piece may be configured to be cut from both the left and right sides.

In the above embodiments, the storage box is used to store a rolled material made of a sheet-like body such as an aluminum foil, but the present invention is not limited thereto, and a general storage box for storing other objects may be used. In this case, the cutting blade may not be provided depending on the stored object.

In the above-described embodiments, the shape of the specific leading edge is configured by cutting out a semi-oval notch or by cutting out in a straight line, and the range of the specific leading edge is set at a position where a part of the specific leading edge is exposed from the left lower folded piece.

In addition, in the above-described embodiments 1 and 3, the notch forming the specific leading edge is formed in a semi-oval shape, but the notch is not limited thereto, and may be formed in another shape such as a rectangle.

In addition, in embodiment 2 described above, the specific leading edge is configured to be cut off by a straight line, but the specific leading edge is not limited to this, and may be cut off by another type of line such as a wavy line.

In the above embodiments, the left lower folded piece and the left lower folded piece are fixed to each other by the 2 nd left rear folded piece, but the present invention is not limited thereto, and may be configured by other fixing portions.

In the above embodiments, the left side rear folded piece and the left side front folded piece are set to have such a length that a part thereof overlaps with each other, but the present invention is not limited thereto, and may be set to have a length that does not overlap with each other as long as the left side rear folded piece and the left side front folded piece are fixed at least to the inside of the left side upper folded piece.

In the above embodiments, the front edge of the left side upper folded piece is aligned with or substantially adjacent to the left edge of the front piece at the connecting portion with the bottom piece, but the present invention is not limited thereto, and the front edge may be spaced rearward from the front piece at the connecting portion.

In the above embodiments, the storage box is configured by a blank, but the invention is not limited thereto, and any other material may be used as long as it has a certain shape retention property and can be bent. For example, the sheet may be made of a sheet-like body obtained by stretching a synthetic resin such as polystyrene or polypropylene.

In the above embodiments, the storage case is fixed by an adhesive, but the present invention is not limited thereto, and may be fixed by another method.

In the above-described embodiments, the storage box has a structure in which a specific leading edge is provided at least at a part of a position corresponding to the removed portion or the removed piece, among two adjacent faces of the rectangular parallelepiped member, but the present invention is not limited to this, and the present invention can be similarly applied to two adjacent faces even if the storage box is another polyhedron.

In the above embodiments, the storage box is formed by bending a specific sheet-like body, but may be formed by another method.

In the above embodiments, the boundary between the divided remaining portion and the removed portion is a specific needle hole, but it is sufficient if the boundary is a cut line that can be freely cut from one direction (left direction) to the other direction (right direction).

Therefore, the storage box according to each of the above embodiments can be described as a configuration below in a modified view.

That is, the storage box 10 according to claim 1 of the present invention is a storage box 10 formed by bending a sheet-like body 11 expanded into a predetermined shape into a rectangular parallelepiped shape including a front surface portion 12, a rear surface portion 13, a flat surface portion 14, a bottom surface portion 15, one side surface portion (left side surface portion 17), and the other side surface portion (right side surface portion 16), wherein the front surface portion 12 is divided into a remaining portion 26 and a removed portion 27 with a cut-off line (needle eye 41) which is freely cut from one direction to the other direction as a boundary, the removed portion 27 can be removed by cutting the cut-off line (needle eye 41), at least a part of one side edge (left side edge 47) of the removed portion 27 is arranged to overlap one side edge (left side edge 42) of the front surface portion 12, and a front edge 48 of the one side surface portion (left side surface portion 17) is arranged to be spaced rearward from the position of one side edge (left side edge 42) of the front surface portion 12 at least a part (specific front edge 58) corresponding to the one side edge (left side edge 47) of the removed portion 27).

With this configuration, since a space is secured between at least a part of one side edge of the removed portion and the front edge of the one side edge portion, it is easy to press a finger against the one side edge of the removed portion, and it becomes easy to pinch the removed portion.
